I was really looking forward to getting this, especially since the three reviews so far are all very positive.
What a disappointment!
The contents are very cheap and nasty. For example, the so-called "echo effect" microphone is just a fixed plastic toy, with a fake "on off" switch which doesn't do anything, it's just part of the moulding, and you would get the same amplification from a banana - i.e. none - but a banana would be funnier and more useful because you could eat it afterwards.
There is a sort of whistle thing in which also doesn't work.
They have so-called "origami paper" - it's just cheap white paper that you could get out of your own printer, except it's square.
The challenges are terrible - they're not singing or dancing, they're things like "build a house of cards" which is not a Britain's Got Talent kind of thing at all. The rules make it clear that the challenges will not get you through the allotted time, you just have to sweet talk the judges (in an unspecified way) to stop them dying of boredom and timing you out.
The rules are very complicated - which is odd - because you would expect it just to be "sing this song and get rated". Not at all. You have a board. You have counters. You have a fiendishly complex scoring system based on difficulty, skill, time before time out. This is not a "get up and go" game you could just get out at a party or when a little drunk after a meal. You would have to study and practise this a little before unleashing it on your friends. And, to be honest, you would have more fun watching paint dry.
I'm sending it back. I suggest that you don't buy it in the first place.
